[PATCH] revision.c: really honor --first-parent

[Lars Hjemli <hjemli@gmail.com>]

In add_parents_to_list, if any parent of a revision had already been
SEEN, the current code would continue with the next parent. But if the
first parent has been SEEN and --first-parent has been specified we need
to break, not continue.
